[Kimchi-devel] [PATCH][Kimchi 2/2] Modify tests to support mem devs with different sizes

Tue May 17 19:15:40 UTC 2016


This patch makes the changes and add tests to check new memory
behavior. It should add (hotplug) a memory device with the additional
memory device amount (instead of devs of 1GB as before).
